ILLUBNATING HECENISM.

Applicaties mea hay 11,

T o all whom. i my confie/v1:

Be it known that l. JoHN T. SIEFERT.

a citizen of the `United States, residing at with a. surrounding eren oflesser brilliancy.

It is my object to provide a headlight.' that has a. particularly bri htbeam of light directed on the roeddirect y in front of the vehicle, atsuch eh ingle that it will not interfere'with the drivers of othervehicles and their vision1 while at the seme time providing an area ofdiffused light which enbles the operator of the vehicle-carrying theheadlight to see the road on either side of the heem of light.

It' is my further object to provide, in the same combination. pilotlights on the top of the lamp or headlight. illuminated from the semesource of illumination.

It is en additional object of my invention to provide in the semeheadlight means of illuminating the ground directly in front andadjacent to thefront wheels, euch illuminetion mining from the samesource of illumination in the headlight.

It is e further object of my invention to provide such an arrangementofparts that m invention may he ep lied to existing headlights Withoutmodi ing. euch heedl ts. 1eerrin, 2 to the drawings:

Figure 1 is e section through the complete eembly of the headlightcombination.

' Figure 2 is e modcetion showing the pplicetion of myinvention to e.@tender om v Rg'ferring to the drawings in detail;

1 is u lamp housing', havin e rededor 2 carried therein for reflecting te light from the electric lamp 3, which is supphed with current bythecable 4. n i

This lamp may he provided wlth the o1'- dinnry` lens, such as found inautomobile ma. semi no. scnes.

headlights, or it may oe provided with the plano-convex lens 5, and asimilar .planoconvex lens 6. which are held in position by the retainingting 7 and the ring 8. These plano-convex lenses have their convexsurfaces adjacent to one another, with their plane surfaces respectivelyadjacent. to the lamp and to the front of the mechanism.

The casing 1 is projected into u. cylindricel. barrel 9. This barrelcarries on the. top thereof a hood 10 and a lens 11, which are adaptedfor the purpose of furnishing e pilot light. lf two of my headlights areemployed, one on either side of the vehicle,

I may color one of these lenses red and the 'other green. At'the bottomof this barrel 9v' is u cuteway portion 12. Below this cutaway portionis a glass 13 through which llight is diilused for .the purposeofillum'n hating the ground adjacent to the front wheels. The lens 14,similar to the lens l1, is provided to further illuminate the roed weyadjacent the front Wheels by the diffused light passing through.

The forward end of the barrel is oon'- verged into a conical structuredesignated 15. This conical structure hastransversely located therein ebarrier 16, having an apex`- ture 17 therein. Within this aperture 17there is located a sliding cylinder 1S, which also has aherrier'desig'nated 19. This barrier has en opening 20 therein. which isrelatively restricted, The cylinder 18 slides within a second cylinder21, whichis carried b v an open throat 22 of the funnelshe'ped structure15. The second tubular member 21 is positioned with respect to thbarrier 16 by a coller v in Figure' 2 will be seen the usuel lam casing1, upon which is slidingly mounts By this telescoping errungement. theorward part of the ymech-- aniism embodying m 1 invention may be mctmtedupon a. sten ard lamp carrying un ordinary lens 25. In operation, thelight furnished by the lamp 3,'heing reected by means of. the redect/or2, passes through the lenses 5 end d, which ere adapted to converge therays e proximetel to the center of the sliding tu e 18. lt is esirebleto have the focus 'Within this tube on e line passing through ythecenter of the tubular members 18 and 21. The

, area of maximiim'illumnstion is' on the line a'-a. This line passesthrough'thecenter of the opening 20, This illuminates` 'the read infront of the vehicle, and such aligns-ed. rays associated with it form abreed triangular-shaped aree of illumination, the oper; of, which is atthe outer end of -the tube 2l, enel the bese of which is removed fromthe machine.4 The depth of this triangular nir-ee is approximatelyeighty feet Jfrom un ordinary sized lamp such as used on automotivevehicles, the base of the trin .enguler aree is approximately twentyvfeet Wicle, providing sufficient illumination for en ordinary residentithe lend adgacent thereto'.

:it will beunclerstoofl that I desireto cornprehend Within. my inventionsuch modifications as muy he fairly embraced Within it, and es maybef'found necessary in adapting it to various conditions in the art inthe course of the application of the invention.

Hering thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent, is:

1, lin combination in en illuminating mechanism, a source ofillumination, e releetor. e lens, e casing, e tubular casing connectedwith the irst easing, e funnel-shaped enel to saicl second casing,having nn aperture' in the apex thereof, a tubular member mounted 1nseid apex of the funnel-shaped mennen lector, e lens, e casing, etubular eesing connected with the rst casing, e funnel-shaped r end toseid second. casing, having an afperture in the apex thereof, a tubularmember mounted in said apex of 'the funnel-shaped portion oi` thecasing, e second tubular meniber adapted to telescope therein, e barrierin 'seid second tubular member having e. restrieted opening, seid sourceof illumination and lens with the reieetor being1 so arranged es tofocus the light on. e line passing through seid tubular members, ecutaway portion in thebottorn of the easing, and e. transparent ,c'overfor 'said opening so formed.
